Using LED glowsticks, flashlights, even fireworks, combined with time-lapse photography, Light graffiti artists create a unique tagging that wraps around objects dimensionally, allowing them to tag in a way they'd never be able to with spraypaint. Very cool!

Wow, I've seen examples of this before, but there truly are some cool pieces of art in there!
Makes me think of buying some stuff and make a couple for IA too!
